To all whom may concern:

Be it known that we, PHINEAS H. ADAMS, Jr., and ORsEt-msl. X.ADAMsitizeus of the United States, residing at (lucano, Illinois, haveinvented certain new and useful Improvements in Apparatus for I'fse inDecomposing' Metallic Salts and Desulphurizing,`

Ores,of which the following is a specification.

The object of our invention is to improve an apparatus for mechanicallydecomposingl chemical compounds, metallic salts, and dcsulphuriziuclores or their resulting' material, when the substances treated are in amolten cmdition, by the act-ion of centrifugal force; and our inventionhas more particular reference to the running-gearemployed in suchapparatus.

In the drawings, Figure l is a vertical section of the apparatus,showing,r the lower p0rtion of the running-gear in elevation. Fig. 2 isa plan view of the running-gear, taken in the line 2 2 ot Fig. i. Fig. 3is a detail of one ot the adjustable boxes of the countershaft, and Fig.at is a detail of the other end.

In making our improved apparatus for decomposin chemicaloompounds,metallc salts, or salts ot' metal, and desulphurizing ores, wemake a receiving-vessel, V, constructed and adapted to receive thesubstances to be treated when in a molten condition. Thisreceivingvessel 'is mounted and rests upon an actuating-shaft, to whichit is fixed or keyed in such a way that by the rotation of the shaft thereceiving-vessel will be revolved. The receiving-vessel may be made insuch way as will secure the required strength and reduce the conductionof heat f rom the interior to the exterior. It may be surrounded by acurbing and have a removable bottom to facilitate the removal of thematerial which is not thrown oft' at the top by the action ofceutrit'ugal force, and in other respects it may be made as will becalculated to subserve the end in view and permit of its being rotatedat a high rate of speed for the separation of particles of differentdegrees ot density in the matter treated. Many of these parts and thedetails ot' their construction, as they do not form the subj ect-matterof our present claims, need not be more fully described, as they will besufficiently understood from an inspection 0i the drawings.

The actuating-sl'iatt A, which serves to rol tate the receiving-vessel,is preferably provided with a flexible joint or coupling', B, to enableits upper portion to have a sufficient lateral play to accommodate it tothe vibrations of the receiving-vessel when rotating at a high rate ofspeed. To assist in maintaining it in its position and restore it to itsvertical position as it vibrates from one side to another, alaterally-yieldable journal, C, may be provided, as shown in Fig. l. Thelower portion of the actuating-shaft is rigidly maintained in itsvertical position by proper boxing, as shown. As the receiving-vessel isintended to be rotated at a speed of several thousand revolutions aminute, and as the actuating-shaft which rota-tes it will revolve withequal speed, while at the same time sustaining its weight with thesuperimposed load, great friction will be produced in the bearing onwhich it rests, and on which it revolves, unless provision be made toprevent it. To reduce the amount of this friction, or rather todistribute it, we have divided the bearing` of the shaft into severalparts or sections, located betweeu the lower portion of vthe shaft or ashoulder or head thereon, so as to sustain its weight, and thestationary bearing` sustaining the. wei ght of the whole, each portionof i the bearing being separately rotatable in the i direction of theshaft and provided with means to rotate it, but at a less rate of speedthan the section of hearing' immediately above it. To this end weprovide a number of sections in the bearii'ig, each provided with apulley or belt-surface, as D and E, connected by belts to pulleys orbelt-surfaces, as F and G, on a power-shaft, H, which is connected withthe actuating-shaft by means ot' a belt, I. The last or lowest sectionof the bearing, of course, rests in or upon a stationary bed or socketadapted to receive it. All of the sections of the bearing rotating inthe same direction as the actuating-shaft, the speed or friction pro`duced in each section of bearing can only be the friction caused bythedifference between its rotation and the rotation of the section aboveit. In this way the friction. speed be- IOO sections of the dividedbearing to secure the g rotation ol' each section ot' bearing at thespeed desired.

As the actuating-shaft will be subjected to a great lateral strain inorder to roi .tate it, caused by/ the pulling of the belt coni neetingit with the power-shaft, thus oeeasioni ing great lateral friction inthe boxes or journals that maintainit in a vertical position unlessmeans be provided to prevent this, we prefer to employ one or morecounter-shafts, as .I 1x', connecting them with belts Il M to theactuati11g-shaft and drawing' them in a direction opposite to thepulling` strain caused by the belt connecting it with the power-shaft.In this way we counterbalance or counteract the .pulling strain in onedirection, and so reduce or prevent extreme and injurious lateralfriction between the power-shaft and its journals. These counter-shaftsmay be located in any position desired, and maybe ofl any preferred sizeor arrangement so long as they enable us to connect them by belts orbands to the actuating-shaft, and so overcome the injurious lateralstrain above explained.

In order to regulate or adjust the tension or drawing strain exerted onthe actuatingshaft by the counter-shafts, we have provided means formoving them toward or away from the actuating-shaft. XVe prefer to dothis by means ol movable journals N O, arranged in slots or grooves inthe frame-work. In Figs. 3 and -lw e have shown both methods ofarrangement. We provide springs I Q between the counter-shafts and theactuating-shaft, as shown in Figs. l an d t. These springs may cient.

yielding' slightly, so as to permit the'countershafts to vibrate inunisonwith the vibrations that may occur in the actuating-shaft or toadjustable toward oifrom t-he actuating-shaft to regulate the tension ofits belt, and with its belt drawing against the actuating-shaft inopposition to the power-shaft to counteract or counterbalance lateralstrain, and means for rotating the actuating-shaft and the seetions ofits bearing, substantially as described.
